Wealthy brat Ethan Couch killed four people, including a mother and daughter, while blacked-out drunk and driving 70 mph on a rural road in June. Defense attorneys said the boy suffered from 'affluenza' and blamed the boy's parents, saying they gave him everything he wanted and didn't teach him about consequences.

"Affluenza," the affliction cited by a psychologist to argue that a North Texas teenager from a wealthy family should not be sent to prison for killing four pedestrians while driving drunk, is not a recognized diagnosis and should not be used to justify bad behavior, experts said Thursday.

The teen’s attorneys blamed his folks’ hands-off approach to parenting, the Star-Telegram says, and they encouraged the judge to remove him from the “toxic environment.” He’ll be sentenced at a later date.

While prosecutors have not named the teen because he is charged as a juvenile, Sheriff Dee Anderson has identified the driver as Ethan Couch.

Anderson said the boy’s blood-alcohol level was three times the legal limit when Couch and seven other teens piled into his red Ford F-350 and sped down Burleson-Retta Road driving 70 mph in a 40-mph zone.

Jennings and the Boyleses were trying to help Mitchell move her stalled Mercury Mountaineer when the pickup slammed into the SUV and then the four victims. Two teens sitting in the Ford F-350′s bed also suffered serious injuries.

At the time, the sheriff referred to the crash as “probably the most difficult accident scene we’ve ever had to work.”

The teen appeared at a detention hearing Wednesday afternoon at the juvenile justice center in Fort Worth and was released into his parents’ custody with an ankle monitor. A trial date has yet to be set.
